A method for service oriented WebGIS construction by integrating open source GIS

With the development of network technology, more and more people choose service-oriented development mode to construct WebGIS. The integration of SOA and Web Service technology has become a trend in WebGIS. However, WebGIS construction is not only an enormous but also a high cost project. Facing this problem, this paper proposed a solution for quick and efficient construction of WebGIS. Firstly, it analyzed the service-oriented development mode and advantages of Web Service. Then it summarized the status of open source GIS and its characteristics. At last, it designed the service-oriented system basing on rich internet application technology and open source GIS. The results showed that this kind of system can fully reflect service-oriented thinking, with a lot of flexibility and extensibility; and it is easy to realize. Therefore, this solution is practical and can be popularized widely.
